XWayland GLAMOR & DRI3 Support Added In Mainline X.Org Server

[jrch2k8]

Is anything special needed to make use of GLAMOR for Xwayland like further patches to mutter? I have built Xwayland from Kristians own Xorg branch a month ago, which already had these changes as far as I know, but in Gnome 3.12 it was still using llvmpipe for Xwayland. The mutter build I'm using is a bit old though. It's the snapshot right after Xwayland DDX support was added since the newest version of mutter don't work with the rest of Gnome 3.12.

this patches only work for intel driver, gallium drivers don't have DRI3 support as far as i know, keith sent a patches some time ago for RFC but i never see them in master, so you need recent intel driver

Interesting.

What about when GNOME supports bypass composting? (I assume it eventually will)
What about when PRESENT support is merged for XWayland? (I assume it will)

What about when comparing using DRI3 instead of DRI2?

Depends on the Present implementation of the DDX.
Looks like the default with the intel DDX when vblank_mode=0 (no vsync) is to do the same thing than the Present fallback.
However it has a parameter to switch to a better mode (in my point of view) that would do flips instead of copies. That should increase performance.

Patches to have DRI3 support for gallium drivers are soon landing in master. They are on the ml and reviewed.

sweet, it seems will be faster than expected , you aware if the patches will require infrastructure at kernel level(not commited yet) for drivers or gallium patches are enough?

No, they work as is.

That doesn't mean their DDX will support them though. (Nouveau DDX support it, but it is disabled for the Amd DDX).
